WOOD CUTTING APPARATUS BACKGROUND OF THE INVENTION The present inventionrelates to a machine for cutting a pattern in the surface of woodenmembers and especially for cutting the surface to resemble a handhewnsurface.

In the past, various hand tools were used for converting trees intoshaped lumber included saws, axes and adzes. These hand tools are ofcourse still used but the production of lumber from logs has been takenover by machinery, such as electrical saws and planing devices forgiving various finished surfaces to lumber. However, it has becomepopular to produce beams resembling those used in colonial and earliertimes which were hand-hewn from logs having a very rough chipped-likesurface. These beams have been simulated with molded, foam plastichaving a wood-like surface coating but such beams typically arerecognized as not being real wood.

New hybrid pine trees have been developed which grow to a usable sizemuch more rapidly than in the past and has resulted in silva cultureoperations which can turn over a tree crop in fewer years and therebyincrease the value of the land. Fast growing hybrid trees are especiallyvaluable in the pulp industry for making paper, paperboard and the likebut many of the fast growing hybrid trees have a larger number of knotsreducing the grade of the lumber that can be produced therefrom andthereby the value of the trees.

The present invention is adapted to taking a lower grade lumber andproducing a finished, saleable product which will increase the value ofthe lumber by the sale of a finished product which resembles a woodenhand-hewn beam surface by the cutting of a pattern in the surface of thewood and staining and assembling the wood into beams. In accordance withthe present invention, lumber has first been graded and had its knotsurfaces cut down or lowered approximately 3/32 of an inch to reduce theforce required to trim the knot and to prevent the present apparatusfrom bur sting or otherwise knocking the knots out of the lumber. Thelumber so prepared is fed into the wood cutting machine where it isfirst planed and then a hewn-type surface is cut into the surface of thelumber which may then be stained and packaged for sale through buildingsupply outlets and lumber yards. It will of course be clear thatassociated machinery is utilized for trimming knots, bevelling surfacesand staining if desired for use with the accompanying apparatus.

SUMMARY OF THE INVENTION The present invention relates to an apparatusfor cutting patterns into the surface of lumber, or the like, and has aframe with a conveyor feeding system for feeding a piece of lumber, orthe like, past cutting blades. Means are provided for aligning thelumber being fed and gripping and feeding the lumber past a planer andthen past the cutting blades. The cutting blades rotate on shafts ridingin a casing which also rotates to produce the cutting pattern on thesurface of the board. Blowers and vacuum attachments are used forremoving wood chips which have been trimmed from the boards. Avertically adjustable table located beneath the cutting blades allowsadjustments to the depth of the cutting by the planer and machinecutting blades.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, andespecially to FIGS. 1 through 4, the overall operation of the apparatus10 is illustrated having a separate console or panel ll. Control panel 11 provides a series of controls 12 in a casing 13 for remotelycontrolling the operation of the separate portions of the machine, aswell as including a master disabling switch in the event the machinebecomes jammed or broken. The switches may be standard open and closetype switches and may have variable voltage controls if desired. Themaster switch may be an interlocking relay, with a circuit using lowvoltage coils and may include a reversing action on the drive. Themachine 10 has a base 14 having a pair of legs 15 mounted on a floor 16.The base 14 includes an outer casing enclosing the machine for safety,and has conveyors l7 and 18 mounted thereon, each conveyor having aplurality of rollers 20 with a pair of roller mountings stringers 21 forfeeding lumber, or the like, into and out of the machine. Conveyor 17has a pair of bracing members 22 for supporting the conveyor to the base14 while the conveyor 18 has a pair of adjustable bracing 5 members 22and 23 for additional support from the base 14. Base 14 includes anupper casing 24 which shields the transmission, cutting blades andcutting blade casing. A cutting blade casing 25 rotates inside of thecasing 24 during the operation of the machine. Gripping roller 27 ispower driven and roughened for engaging the board being fed into thecutters under the cutting casing 25 for feeding the board past thecutters, as well as for holding the board in position during cutting.Roller 26 is a smooth-pressure roller, supported by bell crank at eachend. In addition, a pair of guides 28 and 30 are adjustable for guidingboards of different widths and holding them in a lateral direction. Asimilar pair of gripping rollers 31 and 32 are located on the oppositeside of the upper casing 24 for gripping the board on the opposite sideas it passes under the cutter blade casing 25. A board guide 33 islocated on this side of the upper casing 24. Rollers 27 are mounted inbearings 34 to the side casing wall 35 and roller 26 is mounted inbearing 36 which is pinned at 37 to the side walls 35 and is springloaded by spring 38 to maintain a spring pressure forcing the rollerbearing 36 by means of bell crank 40 rotating on pin 37 to maintainconstant pressure on the roller 26 to compress against the board passingbetween the rollers 26 and 27. Bell crank 40 is threaded from the top toaccomodate an adjustable vertical protrusion 42 and can be fixed by alock nut. The vertical protrusion 42 contacts stationery stop 42 inorder to space rollers 26 and 27 slightly less than the thickness of theboard to be inserted, and of sufficient height to clear guides 28 and30. After the protrusion 42 separates from stop 42, the full adjustedpressure of compression spring 38 is applied, but still allows easyaccess of a board. As shown in FIG. 2, roller 31 is mounted in the samemanner as roller 27 and roller 32 is mounted in the same manner asroller 26 to provide an additional holding of the boards on the oppositeside of the upper casing 24. Rollers 27 and 31 are driven simultaneouslyby the same power source at an identical speed which speed is variableas will be described in more detail in connection with FIG. 4hereinafter. The cutter blade casing 25 rotates while the cutter bladesare rotating therein by the power from a motor 43 through a transmissionincluding a chain drive 44 connected to sprocket gear 45 riding on ashaft 46 mounted in the housing 24, which rotates shaft 46 and therebyrotates sprocket 47 which operates sprocket 48 through a chain drive,driving hollow shaft 50. Shaft 50 is mounted in the casing 24 and isconnected to the cutter blade casing 25 having a plurality of rotatingcutter heads 51 riding on a plurality of shafts 52 located in cutterblade mounting openings 53 of the casing 25. The casing 25 includes anupper casing portion 54 splined to a lower casing portion 55 with theupper casing portion connected to a hollow shaft 56. A housing 57encircles a portion of the cutter blade casing 25 and includes exhaustpipe 58 which may have a suction applied thereto to remove chips andsawdust following the cutting from the wood by the cutter blades 175. Athree-blade planer head 60 may be mounted upon a shaft 61 and driven bya motor 62 through a V-belt 63 for maintining cutting depth of cutters175 in relation to thickness of the board and acts as an aid in throwingchips from the cutter blade up into the housing 57 and pipe 58 forremoving chips and sawduct. This system is enhanced by one or moreblowers 64 driven by an electric motor 65 blowing air into thedirectional outputs 66 on the opposite side of the casing 25 to forcechips being generated by the cutter blades 175 from y the wood passingtherethrough towards the housing 57 and pipe 58 to maintain the areaunder the cutter blade casing 25 relatively clean of accumulated chippedwood and sawdust. An additional cleaning system 67 is mounted on anns 68connected to the base 14 and extending over the conveyor 18 and having ahousing 70 with an exhaust pipe 71 along with an electric motor 72mounted to the housing 70 driving a belt 73 and a pulley 74 which drivesa series of brushes 75 exceeding the width of maximum board width whichrides over boards 76 passing from the cutting portion of the apparatus10 to direct the chips and partially cut fibers, through the exhaustpipe 71 leaving a finished face. Rollers or casters 77 may be mounted bybrackets 78 to the housing 70 or to the arms 68 if desired to maintainthe height of brush 74 in relation to the board surface 76. The legs 15of the base 14 may be mounted with bolts 81 to the concrete floor 16 ifdesired and may be adjusted for levelling the apparatus. However, thelegs 15 and the base 14 have additional bolts 82 passing throughthreaded supporting mounts 83 and into supporting mounts 84. Arigid-surfaced vertically adjustable table 79 located beneath the cutterheads 51 is adjustable with bolts 82 to adjust the cutting depth of theblades 175 of cutter heads 51. In addition, the upper casing 24 isseparated from the lower casing 14 by an arcuate edge 85 and has anangular slot 86 with a bolt 87 passing therethrough along with athreaded support 88 movably pinned at 90 to the casing 24 wall 91. Wall91 is hinged to rotate on pin 89. The threaded support 88 passes throughan opening in support bracket 92 and is adjusted with nuts 93 on eitherside of bracket 92, which may be readily adjusted to vary the angle ofthe entire upper casing 24 and locked in position by nuts 93 and nuts 87along with the rotatable blade casing 25 to align the casing 25 relativeto lumber passing through the machine.

Referring more specifically to the sectional view of FIG. 3, the overalloperation of the apparatus 10 may be more clearly seen by board 94 beingfed upon con veyor l7 rollers 20 where it will pass between the ml lers26 and 27 and be supported therebetween as well as laterally supportedbetween guides 28 and 30 and pass under the planer 61 and into the faceof the cutters 175 of cutter heads 51. In this embodiment, there arefour cutter heads 51 mounted in the cutter casing 25 which are rotatingsimultaneously with one or more blades spaced thereupon while beingturned with casing 25. This spacing on each rotating blade combined withthe rotation of a plurality of blades being simultaneously rotatedproduces a random pattern of cuts and chips from the surface of the woodbeing fed through the machine at variable controlled speeds therebyvarying the pattern being cut by blades 175. This action is controlledby adjustment of varidrive motor 95 of FIG. 4. The board 94 will enterunder the rotating case 25 and be captured by the rotating bladescutting in the direction of the board travel and as the board passes thecenter of the rotating case, the blades again contact the surface of theboard to the same depth against the direction of travel. This eliminatesthe possibility of the appearance of a mechanically cut surface. Thecombination of these actions eliminate the appearance of a circularcutting pattern, due to the rotation of the case, as the cutting arcsappear not to be on a concentric axis. The board is then engaged by thepinch rollers 31 and 32 on the opposite end of the cutter casing 25. Theboard is then fed under the sweeping brush 75 which is an independentunit, exhausting to suction unit through pipe 71. The blower 64 directsair under the casing 25 to the opposite side and enters housing 57 whichis connected to suction unit by pipe 58 and aided by clockwise rotationof knives on the planer head 61. The random surface chipped boardprovides a surface very similar to hand-hewn boards or beams as mighthave been hand worked with an adz.

In FIG. 4 a variable speed electric motor 95 drives dual sprockets 98,which in turn drives chain 97, which in turn drives the sprocket mountedon shaft roller 27 also driving chain 96, which in turn drives thesprocket mounted on the shaft of roller 31. This view also illustratesadditional features of the transmission which includes shaft 46 passingthrough transmission wall 100 into a top transmission casing 101 andbeing connected to a gear 102 therein which is operatively connected toa gear 103 attached to a shaft 104 for driving one shaft 104. Shaft 104passes through the wall 100 through a hollow shaft 56. Shaft 46 issupported by bearings 105 and 106 and is driven by motor 43 throughchain 44 driving sprocket 45. This in turn drives gear 102, 103 andshaft 104. Shaft 104 passes through shaft 56 into the chain casing 25where it drives the plurality of cutter blades 51. Shaft 46 also rotatesthe sprocket 47 which in turn drives the sprocket 48 and shaft 56 whichis connected directly to the chain cutter'housing 25 which rotates thehousing 25. Motor 43, accordingly, rotates the cutter head 51 and thechain and cutter housing 25 simultaneously. Shaft 56 is supported bybearing 17 in the bottom plate 108 and is prevented from sliding throughby the collar 110 attached to bearing 17, and similar assembly 19 underplate 108. Bearing 17 and 19 assure vertical alignment of shaft 56.Shaft 104 is supported by the bearing 112 attached to the floor member100. The upper chamber 1 13 holding the gears 102 and 103 may be filledwith oil, grease or the like as illustrated in FIG. 4.

Referring now to FIGS. 5 and 6, a better understanding of the lumbersupports and guides are illustrated having a fixed but adjustable guidesupport member 30 having a pair of bolts 1 14 and 115 for locking theguide 30 in place passing through slots 116 and 117 allowing for variousadjustments of the guide and support 30. A notched surface 118 preventsinterference with the sprocket and chain 97. Guide 30 fits over theroller 27 and over a base plate 120 but does not extend over the rearroller 31 and the rear chain 96. The guide member and support 28 has apair of arcuate ends and is movably mounted by means of a pair ofparallel arms 121 and 122 bolted to the base 120 and rotably attached tothe arm 128 by members 123 and 124. As the guide member 28 swings on thearms 121 and 122 it is spring biased inwards by spring 125 lockedbetween a bracket 126 and a nut and washer 127 threadedly attached to anelongated shaft 128 on which the spring rides, thereby pulling the shaft128 against the nut 127 and pushing against the bracket 126 attached tothe side wall of the frame. A stop nut 129 is adjusted to contactbracket 126 to adjust the spacing between members 28 and 30 slightlyless than the width of the board used. Shaft 128 is threaded on one endand is movably attached at the other end to a bracket 130 fixedlyattached to the guide and support 28. This system allows a piece oflumber being passed under the cutting surfaces to be supported onrollers 27 and 31 and table 120 and pushed down with rollers 26 and 32(FIG. 2), while being held laterally by the fixed guide 30 and beingspring loaded on the opposite side with the guide 28 as it passesthrough the cutting portion of the apparatus 10. Roller 26 andequivalent roller 32 ride on a bearing 36 attached to a rotatable arm 40pinned at 37 with the roller shaft passing through a slot 131 in theside wall. A threaded shaft 132 is held to the bracket 41 by flangedhead 133, passes through the bracket 41 and through an opening 134 ofthe arm 40 and has a spring 38 attached on the opposite side of the arm40 by means of a nut 141 threaded onto the threaded shaft 132. Athreaded adjustment member 42 allows adjustment of the fixed stoppingposition for the roller 26. The bottom roller 27 is the driving rollerand is attached by members of bearings 34 to the side walls as shown inFIG. 3 and clears through an opening in side wall 14, as shown in FIG.1, but of course can be adjusted for alignment of the roller 27 asdesired. This system advantageously holds the roller from the top andbottom on both sides of the cutting blades and supports it laterallyfrom each edge. The system is both adjustable and is spring loaded toprovide for slight variations in lumber sizes and loose tolerances inthe cutting operation.

Turning now to FIGS. 7 through 13, the operation of the cutting blades,transmission and rotating housing is illustrated in which a motor 43drives a sprocket 142 driving a chain 44 to drive a toothed sprocket 45to rotate a shaft 46 to drive both the housing 25 and the cutting heads51. Shaft 46 drives an upper gear 102 operatively engaging a gear 103attached to a shaft 104. Shaft 104 passes through a shaft 56 to theinterior portion of the casing 25. A geared sprocket 47 is attached toshaft 46 and engages a sprocket 48 attached to a ho]- low shaft 56 whichis fixedly attached to the upper chain housing 54. Thus, by theactuation of a motor 43, both shafts 104 and 56 are drivensimultaneously but at different speeds of rotation, one passing throughthe other. Due to the reversing action of 102 and 103, shaft 104revolves in the opposite direction from hollow shaft 56. Shaft 56rotates the housing 25 having an upper casing 54 and a lower casing 55while shaft 104 passes through shaft 56 and through the top casing 54and has toothed sprockets 143 and 144 attached thereto. Sprocket 143 isheld by thrust bearing 169 against its hub mounting and is operativelyconnected by a chain 145 to a pair of sprockets 146 and 147 attached toshafts 148 and 150. These shafts are supported by fixed collars 151 and152 and supported by insert bearings 181 in each case. Two sprockets 146and 147 and sprocket 143 are all connected by the chain 145 which has anadjustable idler gear 154 applying pressure there-against for taking upslack that might be in the chain 145. Sprocket 144 is similarlyconnected to geared sprockets 155 and 156 by means of a chain 157 havingan idler gear 158 to take up slack therein whereby the sprocket 144driven by the shaft 104 will drive the gear sprockets 155 and 156. Thegeared sprockets 146, 147, 155 and 156 are all identical and run at thesame RPM by a pair of Delta chain drives. The typical bearing is shownin FIG. 9 as 160. It should be noted, however, that variable speedcutter heads can be used for further changing the pattern by usingsprockets 146, 147, 155 and 156 of varying pitch diameters withoutdeparting from the spirit and scope of the invention. Shaft 156 isattached to shaft 162 and is attached to a bearing similar to bearing160. Shaft 161 is attached at the bottom to a bearing 163 in the samemanner as bearing 151 and 152. These shafts all pass through the topportion 153 of the bottom casing 55. The bottom casing 55 is held to thetop casing 54 by means of a plurality of bolts 164. The bottom casing 55in this embodiment has four generally rectangular sections 53 whichpartially enclose the cutter heads 51. Shaft 104 is attached to thesprockets 143 and 144. To assist in assembly and repair a nut and thenuts on bolts 164 allow the lower cutter housing 55 to be removed fromthe machine without disturbing the drive. This allows the complete chainassembly to drop out from the upper bearings of the four corner shafts,along with 143 and 144. This avoids having to remove the complete upperassembly in order to replace cutter heads, bearings, chains andsprockets. The flanged portions of the bearings are attached to thebottom casing 55 with nuts 167 and is attached at an opening 168 in thebottom of the casing 55. Each of the geared sprockets 155, 156, 146 and147 pass through their respective bottom bearings through the top 153 ofthe bottom casing 55 as is illustrated in FIG. 9 and each has a bevelledgear 171 attached to the opposite end of the shaft which engages asecond bevelled gear 172 attached to shafts 52 so that the rotation ofthe bevelled gears 171 will rotate the bevelled gears 172 and shafts 52and cut ting heads 51. Rotating cutting heads 51 actually include ablade support portion 173 anchored to the shaft 52 by key 174 and has asingle blade 175 and a counterbalanced weight 176 mounted on theopposite side which can be replaced with a second blade forcounterbalancing. FIG. shows an alternate embodiment with two cuttingblades. The blades will cut in sequence as they come around inaccordance with the rotation and positioning of the housing as well asthe spacing of each blade 175 during its rotation on shaft 52 and thelocation and speed of travel of the board. The inside cavity 177 issealed and is filled with proper lubricant for chain drives. Greasefittings 178 are attached to cover plate on four separate housingsencompassing shafts of the type of 148 and top bearings. These fourcavities act as reservoirs for top bearings only. Shaft 52 pass from onecavity 180 to the other cavity 180 having bearings 182 on one side, andbearings 183 on the opposite sides thereof with a shaft locking endmember 184 to hold the shaft on one side and a shaft locking member 185to hold the shaft 52 on the opposite side next to the bevelled gear 172.Shaft 52 could also be held in position by sleeves located betweencutting head 51 and easing walls 53. FIG. 10 has a second embodiment ofthe cutting he ad 51 having a pair of cutting blades 175 attached to theblade holding portion 51 attached to shaft 52 and having a key 174 toprevent rotation of the section 51 and the shaft 52. Blades 175 are heldin the cutting head 51 by Allen head set screws, clamping blades 175 tosides of slots in the cutting head 51. Allen set screws are alsothreaded in the bottom of blade 175 in order to adjust the distancebetween the bottom of the slot in the cutter head 51 to correct theradius of the cutting edge, after regrinding to assure accurate depth ofthe cut.

It should be clear at this point that a wood working machine has beenprovided in which lumber of different sizes may be cut to give unusualand random surfaces, such as might be accomplished by a hand adz, in arapid manner for the manufacture of beams for use in the buildingindustry. The lumber being fed into the present apparatus would normallybe treated by having each knot section cut down by a fraction of an inchso that the blades in the present apparatus will not burst knots orknock them out of the wood. The wood may also be bevelled with cuts 187as illustrated in the board 94 of H6. 7 so that upon completion of thesurfacing of the board 94 in the present apparatus it will divide intothree bevelled sections which may then be assembled into a square poston three sides to resemble a larger beam. The present apparatus also isreadily adaptable for various adjustments for changing the size andsurface produced on the wood without departing from the spirit and scopeof the invention. For instance, the shape of the blades could be changedto produce a different surfacing characteristic to the lumber beingtreated. Accordingly, the present invention is not to be construed aslimited to the particular forms disclosed herein since these are to beregarded as illustrative rather than restrictive.
